DFB laser chip (distributed feedback laser chip) is a key device for the integration of three networks (telecommunications network, radio and television network, Internet), cloud computing data center, and 4G / 5G wireless communication network. The manufacturing process is very complicated. At present, DFB laser chip manufacturing technology is mainly in the hands of developed countries such as Germany, the United States, and Japan. This laser pointer technology achievement of Shijia Photonics Co., Ltd. has complete independent intellectual property rights and will fill a domestic gap in this field.
At present, the imported high-resolution lithography equipment, scanning electron microscope, X-ray diffractometer, chip automatic test system, microwave network analyzer, and microwave probe test system for DFB laser chip production have been installed and debugged and entered the product. Trial production stage. So far, the company has invested nearly 200 million yuan in the project.
According to reports, since the beginning of this year, Shijia Photonics Co., Ltd., located in the Hebi National Economic and Technological Development Zone, has not only made new breakthroughs in DFB laser chip projects, but also continuously increased investment in scientific and technological research and development and new product development, as well as the development of several new products. Both have made encouraging progress.
One of the company’s main products–wavelength division multiplexing chips used in data centers–has already been in mass production conditions. It can produce more than 2,000 wafers per month, and can bring in annual sales income of more than 30 million yuan after reaching production; 100G optical transceiver components have also been produced in small quantities. At the same time, taking the opportunity of military-civilian integration, the company established Shijia Information Technology Research Institute Co., Ltd. to actively promote the docking and expansion of the company’s products in other fields.
The company has developed rapidly in the past few years. Last year, it continued to maintain the global leader in passive optical splitter chips and achieved sales revenue of more than 600 million yuan. Key technologies and industrialization projects of optical splitter chips and array waveguide grating chips for optical networks were awarded Second prize of National Science and Technology Progress Award. This year, we will continue our efforts to make breakthroughs in the laser pointer core chip and industrial scale, to give play to the company’s innovative power, and to drive the rapid development of Zhongyuan Optics Valley, which has the core of our city.
